■ WIRING DIAGRAM

■Wiring Precautions: 1. Before wiring, verify the controller label for correct model number and options. 2. For thermocouple input, use the appropriate compensation wire. And note the polarity of input signal. 3. To avoid noise induction, keep input signal wires away from instrument power lines, load lines and power lines of other electrical equipment.
